Ubuntu Servers :: Https:// Leads To Another Site On My Server

A while back, I put a site up under a LAMP setup, and followed a guide from ubuntuforums that I googled to set up SSL encryption for the site.

That site works great, but since then, I've added some other sites to the same LAMP server. They load fine as well, but if I type in https:// before going to the latter sites, the browser attempts to redirect to the first, and warns that it is a fraudulent certificate, and that I'm at risk by going to the site.

Obviously, it isn't an attack site, the certificate is just set up for only one domain. How do I prevent my non-SSL sites from redirecting to the SSL-encrypted site?
